Subject: [PATCH 5.1 099/121] ARM: mvebu_v7_defconfig: fix Ethernet on Clearfog

From: Jan Kundrát <jan.kundrat@...net.cz>

commit cc538ca4308372e81b824be08561c466b1d73b72 upstream.

Compared to kernel 5.0, patches merged for 5.1 added support for A38x'
PHY guarded by a config option which was not enabled by default. As a
result, there was no eth1 and eth2 on a Solid Run Clearfog Base.

Ensure that A38x PHY is enabled on mvebu.

[gregory: issue appeared in 5.1 not in 5.2 and added Fixes tag]
